Have to admit I'm not only new here, but new to Chevs (hides behind flame proof shroud). Although I do have some GM cred as I had a 70 GTO vert I sold last year.
I'm currently looking at a very nice 70 LS5 but being cautious in checking out all the details. The delivery invoice states M21 box but the seller says it has an M22 rock crusher. So I have a few questions for you knowledgeable guys.
Was M22 an option in 70's?
What ID numbers do I look for on the box to tell M21 from M22?
Any other relevant information appreciated.
Cheers,
Peter.
